cellular chickpea flour decreases postprandial glucose
In plain terms: Does coarse chickpea flour lower blood sugar after a meal?
Part of: • Chickpea Flour
Yes, when coarsely milled so starch stays locked in cells; grinding it fine erases the benefit.

No new research arrived. Two of the trials supporting this claim were recorded as separate studies but are one: a King's College London crossover trial (registered NCT03994276) in which the same twenty volunteers ate bread made with 0%, 30% or 60% cellular chickpea flour. A 2021 paper reported their blood-glucose results and a 2023 paper reported their gut-hormone and insulin results. Both point the same way and both still count — but as one study, not two. The finding is unchanged; we were counting a single trial twice.

How the studies fall
What the evidence shows
Coarse, cellular chickpea flour attenuates postprandial glucose; fine milling erases the benefit (cell-wall encapsulation of starch is the active mechanism).

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
